FOUNTAIN-PEN.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed November 19, 1907. Serial No. 402,857.

To all whom it mag concern:

Be it known that I, FERDINAND H. WURDE- MANN, a citizen of the UnitedStates, residing bent away from the feed device which causes vof thenib, as clearl shown in an excessive flow of ink or no ink at all.

The present invention is designed to remedy this defect, and itcomprises an attachment in the nature of a small metal tongue which isattached to the pen-barrel and bears on theu pe'r surface of thepen-nib, forming a stop to nib away from the feed device.

In the accompanying drawings, Figure 1 is a plan view showing theapplication ofthe invention, only so much of the fountain pen beingshown as will sufiice to show the connectlon of the invention herewith.Fig. 2 is a side elevation. Fig. 3 is a central longitu dinal section.Fig. 4 is a perspective view of the attachment removed from the pen.

In the drawing, 5 denotes the pen-barrel which contains the supply ofink; 6 is the nib; and 7 is the feed device. These parts are arranged inthe usual way and nothing is claimed with respect thereto.

The attachment comprises a thin strip 8 of brass or other metal which issecured in the bore of the barrel 5 by being inserted between the innerwall thereof and the u per surface Fig. 3. The strip projects from t efront end of the barrel and-at its outer end is bent downwardly asindicated at 9, to bear on the upper surface of the slitted portion ofthe nib sli htly to the rear of the outer end of the fee device. Theedge of the strip in contact with the nib is made concave, as shown inFig. 4, to conform to the curvature of the nib.

unit the movement of the On the back of the strip 8 is a projectingpinlO, having a head 11, and the barrel 5 has a slot 12 to receive thepin. By means of the pin the strip can be readily slid back and forth toadjust the point of its contact with the nib.

The attachment herein described forms a stop and prevents the nib frombeing bent from the feed device from long con-- away tinued use of thepen, and the space between the nib and the feed device can be readilyregulated by adjusting the strip. Upon sliding it inwardly the nibispressed toward the feed device, and moving it outwardly increases thedistance between the nib and the feed device. It is therefore possibleto regulate the flow of ink at all times and the attachment also keepsthe points on the nib even, and prevents dropping of ink. The attachmentcan be cheaply manufactured and easily applied to any ordinary fountainOn the bottom of the strip, near its outer end, is a small knob 13 whichfits the enlarged inner end of the slit of the pen-nib,

and is for the purpose of preventing atoo free flow of ink. As the feedof fountain pens varies, this knob may in some cases be wit free flowingpens.

I claim i 1. In a fountain pen having a feed device on one side of thepen-nib, a stop to limit the movement of the nib away from the feeddevice, anda protuberance on the stop engageable with the back of thenib.

2'. In a fountain pen having a slotted barrel and a feed device on oneside of the pennib, a tongue slidably mounted in the barrel and havingaprojecting pin working in the slot of the barrel, said strip projectingfrom thle barrel and engaging the other side of the n1 In testimonywhereof I affix my signature, in presence of two witnesses.
